' Application fued september e, 1923. serial Nofceioa Be it known that I, NORTON A. Nuwnron, a vcitizen ofthe United States, residing in Columbus, in the county of Franklin, State of Ohio, have invented certain new and useful' Improvements in Conveyers, of which the following is a specification.

vThis invention relates to limprovements in conveyors and is especially directed to an improved drag` conveyor of aftype conslsting of a plurality of longitudinally extending transversely spaced endless chains, having connected therewith transversely extending longitudinally spaced flights or carrying blades, and one of the principal objects Of the invention is to provide an'11nproved connection between said chains and flights whereby the chain will be Vfreely flexible for passage around sprockets Vor the like, and at the same time anexceptionally strong and durable connection provided adapting the flights for operation under severe loads. In accordance with the invention therey is provided a conveyor 'wherein the longitudinally extending chains are composed of a plurality of :flexibly Y united links, having their adjoining ends connected by pins,

aro-und which the links pivot and said pins being provided between the links with rollers, adapting the chain for travel over a plane surface with but a minimum of resistance and friction, and in connecting the inner ends of certain of said pins with :ingle brackets to which the transversely leX- tending flights are rigidly secured, the con* struction being such that the flights aresupported in connection with a plurality Of pins, producing thereby a substantial con-` struction which Ypresents an improvement over conveyers of this type wherein Vthe flights are connected with oE-set flanges or lips provided laterally on the links of the chains.

Another object of the invention resides incons'tructing the connection between the flights and the chains so that the said flights will be maintained in spaced relation from the plane surfacev over which the conveyer operates and which constitutes the bottom of-'fthe conveyer.

'fWVith these and other objects in view that will appear as the description proceeds, the invention consists in the various novel features of construction, Combination ofelements and arrangements of parte,v hereinafter fully described vand pointed out in the appendedclaims, y Y

In the accompanying drawings: Figurel 'is a plan view of a drag con- -veyer constructed in accordance .y with the features of the present inventiongl Figure 2 is a vertical longitudinal sec'- tional view' taken. on the planCindieated by the line2-2 of Figure l( n y Figure 3 is 'a transverse vvertical sectional view taken on the linef?) of kFigure l.:

The said trough is also provided with upstanding sides 3. Arranged 'for Atravel through the` conveyor over the surfacem2 and between the sides 3 1s` aconveyer which,

when vconstructed in accordance with the A present invention, comprises a pair of longitudinally extending, transversely spaced endless chains Ll, which .chainsin this instance are constructed to include a plurality of links 5, having the adjoining'ends thereof provided with registering openings 6 for thev reception" of pins 7,' used in pivotallyv uniting the adjoining ends of said links and to render the chains flexible `in a single plane. The' said pins are provided between the ends of the links with rollers 8, which are arranged to restvdireotly upon the sur# face 2 of the trough, thereby causing the same to produce a rolling friction on the trough andftherebyv reduce friction losses. EXtendingf-between the chains@ is a plurality of transversely disposed;V longitudinallyspaced flights 9, which in .this'instance are of angle Construction and-include vertical webs". l0 and horizontally disposed webs 11 which,-:aa's shown in Figure`j`2, are arranged immediately above the surface 2 and out of engagementtherewlth. The ends of the flights are connected with the inner sides ofthe chains so as'to move iii unison With salchicha-iris, whereby when theY con-A veyor is in operation material deposited or disposed in lthe trough l will be engaged by the vertical Webs ofthe flights 9` aifd 4caused to travel in unison with the conveyor over the upper surface 'of the trough 1, said surface constituting the bottom of the trough, and the conveyer described is particularly useful inhandling coal or other substances of alike grittyfnature, and the chaink is substantially constructed to adapt itselfvto materials foi this description. -In this connection the horizontal web 1 1 of each yof the lflights Q' is provided to reinforce,

strengthen or brace vertical material en fag-me' Webs l0, .eliabllng the latter to resist the bending or breaking stresses which the materials being conveyed exercise there- InpriQr construction in QQDYGYGrS of this lin, s themselves and' associated"parts.v To

mid this'and to produce a stronger chain QD@ Wlititin repairs my bema'de quickly and eonveniently,the` present invention provides attachment between the flightS and linlisivhich consists of a plurality of angle`v brackets l2. 'TheSe .brackets are formed to include transversely extending armsand are'y arranged in pairs'so as to reV ive betivecn them'yfertical Webs l0 of the llio'hts. Rivets or other "fastenings ll .tre usedto unite the arms 13. with the ends 'lhe inner ends of the arms 1,34 terminate in dowlirvardly and outwardly @steuerte 'relatively @U1/'erstes @es L5 which are apertured to receive inner ends oli` the pins 'Tieniployed Vinthe chain construction, upon Which pins the'load on the flights is received. By this it Will be observed that the load on each flight isfdistributed upon four pins, instead of being placed upon the links ot' the chain.y Furthe-r7 by the connection any tendency on the part oit' the flights to rock or rotate is effectively'precluded and the horizontally eX- tending webl of each flight maintained in spaced relation from the surface 2.y Thus', the construction avoids the use of special links, 'asis the practice in Plior conveyers o fthis type, in v the chains 4;, permitting.' the use ot standard chains' through and yet produces a" more substantial and durable construction lwith' a better distribution there? e111 of Werking Stretses and Strains! The angle brackets'lmay be readily formedby uttiil@ the sun@ n a bits l0f Steiidtltl ah eA stock.l Certain of the pins'(w may be provided' with openings in the inner ends thereof for the receptibnof cotter pins 16, permitting the'chain to be readily assembled or disassembled and repairs or replacements made" That is claimed is: y

l. In a conveyer, a chain formed to coinpr'se'a plurality 0f links; Pivottil ConnettOis between] the ttlilflns' ends. Oftd links permitting the chain to'flex in single plane, a pair of comp'lemental brackets" carried a pair ofhdjoining vpivotal/connect-ions bctveen Said links, and a material y. i l conveying flight rigidly connected with said brackets; y

2. In a cQllveyer, a chain including a plurality of linls having flexible connections between the ends thereof, a pair of upward- 'ly attending brackets carried by an adjoining pair of "said pivotal connections, and a flight Connected with said' "brackets in a plane above that of thev pivotal connectQnSl i Y Y Y i In testimony Vwhereof.
